Randomizer MIDI plug-in in Logic Pro for iPad
The Randomizer plug-in randomizes incoming MIDI events in real time.
Randomizer parameters
Event Type pop-up menu: Choose the MIDI event type that you want to randomize.
Input Range Low and Range High sliders and fields: Set the upper and lower limit for the range of values that are affected. Only parameter values that fall within the range are processed. All values outside the range pass through the plug-in.
Note: You can position the Input Range Low slider above the Range High slider and vice versa, which inverts the input range behavior: events that fall within the range are not processed and events outside the range are randomized.
Probability knob and field: Increase or decrease the likelihood that an event is randomized within the set range. This impacts the Weight parameter setting: a lower value means less chance, and a higher value means more chance to produce value changes in the respective range.
Random Amount knob and field: Set the intensity of randomization.Seed slider: Specify a starting point (or seed) for randomization.
An example is when using the Randomizer plug-in to randomize a piano melody. If you bounce the piano part, your randomized melody is saved as an audio file. If you bounce the song again, with Seed set to Random, the two bounces sound different. If Seed is set to the same specific value for both bounces, they are identical.
Weight knob and field: Determine the event values that you want to favor for randomization. This works in concert with the Probability, Low/High Range, and Random Amount controls.
Set toward the left to increase the chance of low values being randomized.
Set toward the right to increase the chance of high values being randomized.
In the centered position, neither low or high values are favored, resulting in the entire range of values being randomly altered.
Output Offset slider and field: Offset the (random) MIDI output of the plug-in. Offsets can be negative or positive.
